To all whom it may concern:

Be it known that I, EDWARD W. LEECH, Jr., a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Spring Oilers; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apperta-ins to make and use the same.

My invention relates to spring oilers- Among the objects of my invention are To provide an oiler which can be readily applied to the ordinary leaf springs employed in vehicles.

To provide an oiler-which can be readily removed frorn'the spring for the purpose of cleaning and the insertion of new oil dispensing materialj r To provide an oiler which can be readily refilled without removal from the leafspring.

These .and other objects of my invention will be explained in the following specification, referencebeing had to the accom panying drawings, and the means by which said objects are effectuatedwill be definitely pointed out in the claims.

In the drawings Figure 1 is a side view of a leaf spring equipped with a pair of my improved oilers. Fig. 2 is an enlarged section along the line 2-2 in Fig. llooking in the'direct ion of the arrows. i

Fig. 3 is a detail 'viewof one of the oiling members shown in Fig. 2.

Fig. 4 is a view ofthe parts shown in Fig. 2 looking in the direction of the arrow 4 in said figure, the spring 10 being omitted.

Fig. 5 is a section along the line 55 in Fig. 3 looking in the direction of the arrows.

Fig. 6 is a view of my improved oiler looking in the direction of the arrow (i'in Fig. 2.

Fig. 7 is a section along the line 7-7 in Fig. 5 looking in the direction of the 'arrows.

Fig- 8 is a partial view of the upper projection viewed in the direction of the arrow Sin Fig. 3.

I In the drawings 10 is a spring having the'usual plurality of leaves and 11 is the oiling member of my improved oiler which may be applied to'either side of the spring 11 and is yieldingly held thereagainst as hereinafter explained.

The member 11 comprises a. reservoir 12 of the projection 17 faces 23 and 28.

for the oil 13 and the wick 14 is the means for distributing the oil from the reservoir 7 .12 to'the side of the spring 10.

A dust guard 15 is cemented or otherwise secured around the opening in the reservoir 12 through which the wick 14 protrudes.

The reservoir 12 is provided with a screw hole closed bythe screw 16 to providemeans for introducing oil within the reservoir 12.

A lower projection 17 is formed integrally with the reservoir 12 and is provided with a nose 18. The upper projection 19 is hinged as at 20 to the reservoir 12 and is provided with a nose 21.

The projections 17 and with coupling surfaces 22' and 23, respectively, the former being atrig'ht angles to the upper surface of the projection 17 and the latter at an oblique angle'to the lower sur face of the-projection 19.

19 are provided y The clamp 24 is provided with a hole. 25.

for'the passage therethrough of the end26 Said "clamp is also provided with a slot 27 for the reception of the projection 19 and coupling surface 28 located to engage the-couplingsurface 23' on the projection 19. V

In the clamp 24 there is threaded the ad justingscrew 29 which serves to adjust the spring 30.

The operation of my improved spring oiler is as follows The screw 29 being turned backwardly as far as possible without disengagementfrom the clamp 24 and. the latter not being in engagement with the projections17 and 19, said projections are passed over thespring 10, the projection 19 being atthe top thereof. The end 26 isthen passed-through the hole-25, the right end of the projection 19 is then lifted and the upper end of the clamp- 24 is moved thereunder toward the left un- 'til the end 31 of. the projection 19 will pass the outer edge of the surface'28. The

projection 19 is then tov be moved downwardly'and the upperend of the 'clamp24 moved toward the rightto engage the sur- The screw 29 is then adjusted until the spring 30 produces the requisite amount of pressure upon-'thespring 10.

of the clamp 24 toward the right, thus pressing the surface 28 upon the surface 23. ,A part of this pressure results in a downward e It is to be noted. that the pressure ofwthe spring 30 (see Fig. 2) ,presses the upper end pressure of the nose 21 upon. the spring 10 and the reaction to this pressure is a pressure of the'nose 18 upon said spring.

The reaction of the direct pressure of the spring against the spring 10 is a pressure of the dust guard 15 against the spring 10.

Thus it will be seen that by the use of one spring I resiliently secure my improved oiler to the spring 10 and thus securely hold my oiler in place with practically no increase of the friction between the leaves of the spring 10.

It is also to be noted that my improved oiler may be applied and removed without the use of tools.

While I have shown one combination of elements for carrying out my invention, it is understood that this combination is ex hibited for purposes of illustration only and not in anywise to limit the scope of my invention, for many changes may be made in the structure shown without departing from the spirit thereof.
